=== EDuke32 ===
A month after the game code, the source for EDuke 2.0 was also released,<ref>{{cite web|url=https://rtcm.site/knowledge-base/downloads-rtcm/src-eduke-source/|title=Source Code: Matt Saettler's DOS EDuke|author=Corvin|website=RTCM|date=10 May 2013|access-date=13 December 2024}}</ref> followed by the source for the last private beta of ''EDuke'' 2.1 (which never made it to a release version). Richard Gobeille (TerminX) merged the EDuke 2.0 source with JFDuke3D to make ''EDuke32''. Another port, ''Wineduke'', based on the icculus code, has since died off, leaving EDuke32 the only EDuke port still in development.<ref>{{cite web|url=http://fps.maros.pri.ee/index.php?event=24|archive-url=https://web.archive.org/web/20230130083444/http://fps.maros.pri.ee/index.php?event=24|title=WinEDuke|website=FPS Ports|archive-date=2023-01-30|access-date=2024-05-16}}</ref>

EDuke32 also supports the games ''NAM'' and ''WWII GI'', as EDuke was based on the code to those games.

==== Polymer ====
On April 1, 2009, an OpenGL shader model 3.0 renderer was revealed to have been developed for EDuke32, named ''Polymer'' to distinguish from Ken Silverman's ''Polymost''. At first it was thought to be an April Fools' joke, but the renderer was later made public. It allows for more modern effects such as real-time dynamic colored lighting and shadow mapping, specular and [[normal mapping]], and other shader-based features in addition to most of the features added to Polymost over the years. Although Polymer is completely usable, it is technically incomplete and unoptimised, and is still in development. The developers of EDuke32 have stated that once Polymer has been rewritten for speed, it will supplant Polymost completely, as it is a superior renderer, and can be made to look identical to Polymost.
